Zurich Cloud Migration Strategy

Overview

Zurich partnered with SevTech to define a comprehensive Cloud Migration Strategy, enabling the transition of critical applications from a legacy London-based data centre to a multi-cloud environment leveraging AWS and Azure.

SevTech conducted in-depth assessments, facilitated workshops with key stakeholders and developed a structured roadmap to ensure a smooth and risk-mitigated migration. The strategy aimed to optimise cloud adoption while aligning with Zurich’s business objectives, IT governance and operational needs.

Challenge

Zurich needed a structured and strategic approach to migrate 59 critical applications to the cloud while maintaining operational resilience. Key challenges included:

• Selecting the optimal cloud provider for each application.

• Ensuring minimal disruption to business operations.

• Managing dependencies between cloud and on-premises applications.

• Aligning with Zurich’s global IT governance, security and compliance standards.

Results

• Phased Migration Plan: A structured, risk-mitigated approach for transitioning applications.

• Optimised Cloud: Each application aligned to AWS or Azure based on its needs.

• Robust Governance Model: Defined roles and responsibilities across Zurich, DXC and CCOE.

• Future-Proofing IT Infrastructure: A scalable cloud strategy supporting Zurich’s long-term digital transformation.

Solution

SevTech conducted in-depth assessments of Zurich’s application landscape, evaluating each application’s suitability for AWS or Azure. A four-phase migration approach was defined, starting with pilot applications and progressing to more critical systems.

The strategy incorporated a tailored operating model, a governance framework and a clear RACI structure, ensuring seamless execution while aligning with Zurich’s Cloud Centre of Excellence (CCOE) and DXC, its managed service provider.
